Title: Improvements in vending machines
Inventor: DAVIS OSCAR BARSACH
IPC: G07F11/54
Filed: 1960-09-29
Abstract: 961,540. Coin-freed vending apparatus. H. V. DEVELOPMENTS Ltd. Sept. 28, 1961 [Sept. 29, 1960], No. 33479/60. Heading G4V. A machine for vending articles such as books comprises a display turntable 15 carrying the books radial-fashion on supports 22, 23 disposed around the periphery of the turntable, a fixed plate 19 overlapping the backs of the books and preventing their removal, a handwheel 29 for rotating the turntable to bring a chosen book under a cut-out 41 in the plate 19 and a spring-loaded shaft 43 which, on coin insertion, rotates a plate 42 away from a blocking position under the cut out. The plate 19 has a lockable centrally hinged section and the books are loaded by opening them about their middle and sliding them down about the vertical plate 23 until they rest on the plate 22 with their backs near a support rod 21 and their sides held by spring clips 25. Each rod 21 and plate 22 is welded together and the rod is extended to form a roller crank 33 engaging in a fixed cam track 16 which slowly rotates the rods to prevent jamming and at one or two positions 40 turns the books through an angle that allows them to be inspected. A roller 48 on a spring-loaded lever 49 engages between piped pins 47 to give a "click" action to the turntable rotation. On inserting a coin through a slot 45 in the plate 19, a solenoid 66 is momentarily energized to withdraw a pawl 57 from a plate 61 on the shaft 43 and a spring 73 rotates the shaft 43 so that the blocking plate 42 clears the cut-out 41 to allow removal of the book. A keeper plate 62 is pulled by a spring 64 into position to prevent the pawl 57 from re-engaging the plate 58 until the shaft has moved fully and a plate 44 is moved under the coin slot to prevent further coin insertion. A pin 52 for the roller 48 lies in a circumferential section 55 of an L-shaped slot 56 and locks the turntable against rotation. To reset the machine, the next operator returns the handle 46 on the shaft 43 to its original position and the pawl 57 engages the notch 60 in the plate 61. A second notch 68 on the plate 61 prevents "see-sawing" of the turntable to a new position as the handle is being returned.

The dispersed phase of a cationic or acid aqueous emulsion, suitable for use in the surfacing of roads, comprises a natural or synthetic rubber latex and a hydrocarbon binder, such as bitumen and tar. The rubber latex is stabilized by an amine dispersible directly in water, a nonionic emulsifying agent, or an amino-acid, Amines dispersible in water may correspond to one of the following formulae: wherein R is a saturated or unsaturated hydrocarbon radical having 12 to 18 carbon atoms, and R<SP>1</SP> is a hydrocarbon radical, preferably saturated, having 1 to 4 carbon atoms, and may be used in a preparation of 5 % to 20% by weight of the latex; the nonionic emulsifying agent may be an ethylene oxide derivative of an alcohol, acid, ether, phenol, amide or amine used in a proportion of 2% to 10% by weight of the latex; the amino-acid may be the hydrolysate of casein or gelatine used in a proportion of 2% to 50% by weight of the latex. The hydrocarbon binder is a pure or fluxed bitumen or a tar-and-bitumen mixture of which either may have been fluxed by anthracenic or phenolic oils. The proportions by weight of rubber and hydrocarbon binder relative to the total weight of the emulsion are 2% to 10% and 40% to 70% respectively. In manufacturing the emulsion the latex is stabilized by the addition of one of the class of stabilizing agents mentioned above, and to the stabilized latex there is added an emulsifying agent for cationic emulsions constituted by an amine, the major part or all of which has been neutralized by a mineral or organic acid to provide an acid addition salt of the amine, e.g. amine hydrochloride, the resulting mixture being diluted with water. Examples are given.
